Scenario 1

Questions 1, 2, 3 and 4

Faster Cars is a racing car company that produces high-speed racing cars.

The company uses CAD/CAM.

The company employs engineers and mechanics to maintain the cars. It has an expert system that can be used by the mechanics when trying to diagnose faults in the car engines.

The company has its own racing drivers who use simulators to practise high-speed racing for when they are driving the real racing cars.
